Practicing Taiwanese at the Supermarket

I go with my mom to the supermarket. A store employee helps us bag our few items. His name tag says "Chen" and he's Chinese.

I can't help asking, "You speak Chinese?"

"Yes, I am from Taiwan."

I start speaking to him in Chinese. I insert the little Taiwanese I know. He starts talking to me in Taiwanese, but I tell him to that I don't speak Taiwanese, just a few words.

I am happy. I tell him I just lived in Taiwan for a year, that I am here visiting my mom.

"Welcome!" he says in Chinese.

I want to come back everyday and talk to him
